So, I did as PrettySmallThings recommended, and designed my own firebox. It's getting to be that time of year, and I thought a mini fireplace with an electronic tealight would make a nice desk decoration.
I do not recommend using this design with a real tealight. I have not tested it, and it could damage or melt PLA. An electronic tealight should be a snug fit.
I recommend using supports. The tree cutouts require them. My image after print is a little rough from removing the the supports and stringing. I also printed at a low quality layer height for speed.
